I honestly just stick with X11 because of the high degree of compatibility, and I often already rely on X11-only software anyways like Redshift (I know there's Wayland-supporting alternatives, but I'm picky and don't like switching if I don't feel I need to), also my DE/WM of choice is currently awesomewm and I think I've heard mixed things about using awesomewm on Wayland (or it might not even be compatible at all. I just woke up and I'm struggling to remember lol)

Either way is fine usually. If you really care about 1:1 trackpad gestures like I do, get Wayland. If you have an nvidia card, get x11. Otherwise it’s probably not something most people will even notice.

Both of them have issues depending on the setup. X11 has worked flawlessly in my experience. Wayland has worked the same for most.

Personally, Wayland still has some growing pains, especially in regards to Input handling (mouse, keyboard, etc). In X11 it was "trivial" to edit one file and have the settings stick across different WMs (switching from DWM to i3, etc.) There's no standard for this with Wayland since it's up to the compositor to handle these things, meaning you're relearning how to do something as basic as setting pointer speed each time you try a new compositor. This is my only real fair gripe about it currently, as the rest of my complaints are just due to how young a lot of the Wayland-specific tools are - this will improve with time.

x11 cuz xfce also .. i want a just working system^^

I still use X11 because one of my necessary voip apps (mumble) doesn't yet support wayland's method of global hotkeys.

Otherwise I don't particularly care one way or the other.

Wayland, works better with games. Unless it's star citizen, then x11 because it somehow breaks the elevators

X11 for xdotool. ydotool doesn't support (& can't really support with it's current architecture) retrieving information like the current mouse location, current window, window dimensions & titles. Also, normal (unprivileged) user ydotool use requires udev rules or session scripts and/or running a ydotool daemon & many distros don't yet ship with this Just Working.

X11 for Alt-F2 r to restart Gnome Shell without ending the whole session. This is a useful workaround for a variety of Gnome bugs.

X11 because my current setup on Wayland crashes constantly, otherwise always Wayland.

X11 because i3wm

Wayland. It's super smooth and supports new display features.

Everything works, but I don't really use global keyboard shortcuts.

Doesn't Wayland only work with Amd Gpus?

I use xpra which lets me run persistent seamless windows from my VMs and remote servers. It would probably work okay with xwayland but i might as well keep using X. I understand why people use Wayland though and would recommend it to newcomers.
